SPECIFICATION forming part of Letters Patent No. 619,648, dated February 14, 1899.

Application le. October 6, 1898.

T0 @ZZ whom it may concern:

Be it known that I, HARRY J. WILLIAMS, of Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Cork-Extractors; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

The invention relates to improvements in power cork-extractors or such as are designed to be attached or clamped to a counter or table and operated by means of a handle or lever; and the objects of the invention are to produce a simple and powerful mechanism which will with one reciprocation of the handle force the corkscrew into the cork, extract the cork from the bottle, and discharge the cork from the screw, leaving the parts in position for the next succeeding operation.

Referring to the accompanying drawings, Figure lis a vertical sectional view, partially in elevation, showing the position of the parts when the handle or lever has been moved forwardly and the corkscrew forced into a cork within the mouth of the bottle. Fig. 2 is a similar view showing the position of the parts when the cork has been withdrawn from the mouth of the bottle and the handle or lever has moved part way back to normal position. Fig. 3 is a similar view illustrating the position of the parts in their normal position or when the handle has been moved to a position to discharge the cork and to leave the parts ready for a subsequent operation.

Like letters of reference in the several figures indicate the same parts.

The letter A indicates the frame or body of the instrument, which is preferably formed with a clamp B for attachment to a counter or like support and which may be varied indeiinitely to suit the particular conditions under which the device is used. The front portion of the frame or body A is made in the form of a cylinder A', preferably somewhat inclined to the perpendicular for convenience in presenting a bottle to the extracting mechanism. Immediately in rear of this cylinder a chamber A2 is formed for the reception or accommodation of a worm-wheel C, mounted Serial No. 692,825. (No model.)

the shank D serving both as a rack and as worm-teeth in accomplishing these motions. The lower end of the shank D terminates in or has attached to it in any suitable manner a corkscrew E, the spiral of which runs in an opposite direction from the thread on the shank D. Thus if the threads on the shank D are left-handed threads the spiral of the corkscrew is a right-handed spiral, and vice versa. The corkscrew works through a nut F, mounted in the lower end of the cylinder A and held against rotation by a screw f, working in a slot f inthe cylinder, which slot f also permits the said nut to move longitudinally in the cylinder a distance corresponding to the necessary longitudinal movement of the corkscrew in withdrawing the cork from the bottle, and the action of this nut F when the shank and corkscrew are thrust down is to cause the said corkscrew to rotate forwardly and enter a cork if the same is presented in proper position.

The longitudinal movement of the shank and corkscrew in an upward direction is limited by a cap or plug Gr in the upper end of the cylinder, and in order to eliminate friction in the rotation of the shank and corkscrew when at the upward extreme of its longitudinal movement the end of the shank is preferably reduced, as at d, and adapted to coperate with a cone bearing in the under side of the cap at g, Fig. 2. If desired, however, a ball-bearing of any well-known construction may be introduced in the cap, as indicated, for instance, at g in Fig. 1, it being understood, however, that any well-known form of bearing may be substituted Without departing from the invention in the slightest.

With a device constructed as thus described when it is desired to extract a cork, assuming that the parts are in the normal position indicated in Fig. 3, the bottle is presented to the lower end of the cylinder and the handle IOO the nut F will cause the screw to rotate for-. wardly and penetrate the cork, and, secondly,

by reason of the inclination of the teeth on the shank D the tendency of the said wormwheel C will be to cause the said shank and corkscrew to rotate, thus there is imparted to the shank and corkscrew a tendencyto rotate y forwardly through two separate mechanisms-that is to say, through the action of the worm-wheel and the worm and through the action of the nut F, operating directly on the corkscrew. The screw having now penetrated the cork to the position indicated in Fig. l, a reverse movement of the handle will cause the worm-wheel and threaded shank to operate as a rack and pinion, withdrawing the cork from the 4mouth of the bottle and raising the nut F to the upper limit of its movement or until the upper end of the shank stri kes the bearing g, when its further upward longitudinal movement will be arrested, when the 'worm wheel and threaded shank will again operate to rotate the said shank and corkscrew in a reverse direction, such reverse rotation causing the n ut F to travel down the corkscrew and drive the cork o from the same, the parts then assuming, as the handle is drawn backwardly, the position indicated in Fig. 3, ready for a subsequent operation.

Having thus described my invention, what I claim as new isl. In a corkextractor,the combination with a frame or housing,of athreadedshank working in said frame or housing, a corkscrew forming a prolongation of said threaded shank, a longitudinallymovable nut through which said corkscrew works, and a toothed wheel meshing directly with the threaded shank with `a handle or lever for reciprocating said wheel; substantially as described.

2. In acork-extractor the combination with a frame or housing having a cylinder therein, of a screw-threaded shank working longitudinally in said cylinder, a corkscrew-spiral forming a prolongation of said screw-threaded shank, a nut working longitudinally in said cylinder and surroundin g the corkscrewspiral,a bearing forlimitin g the upward movement of the shank and screw, a toothed wheel journaled in the frame or housing and meshing directly with the threads ot' the shank, and a handle or lever for oscillating said toothed wheel; substantially as described.

3. In acork-extractor,the combination with a frame or housing having a cylinder therein, and a cap or plug for closing the upper end of said cylinder, of a screw-threaded shank working longitudinally in said cylinder having areduced upper end for cooperating with said cap or plug to limit the upward movement of the shank, a corkscrew-spiral forming a prolongation of the lower end of the shank, a lon gitudinally-movable nut through which said corkscrewspiral works, held against rotation with said spiral, a toothed wheel journaled in the frame or housing and meshing directly with the threads of the spiral shank, `and a handle for oscillating said toothed wheel to move the shank and corkscrew-spiral longitudinally and to impart thereto a rotation when the longitudinal movement of the shank is resisted; substantially as described.

4. In a cork-extractor the combination with the frame or housing having a cylinder formed therein and a worm-wheel journaled in said frame or housing with a handle for oscillating said worm-wheel, of a screw-threaded shank with which said worm-wheel meshes, located in said cylinder and adapted to move longitudinallyandzto rotate therein, a corkscrew-spiral forming a prolongation of the said shank and arranged with its spiral at an opposite inclination to the teeth on the shank and a nut workingin the lower end of the cylinder and surronding said spiral with `means for preventing the rotation of said nut; substantially as described.
